Abstract: The video game machine of the invention consists of a space located in the game cabinet for receiving the video monitor where a support plate is located on either side of the space and where each support plate includes a pair of tracks. The video monitor is provided with lugs extending from the sides of the monitors that face the support plates. The lugs engage the tracks such that the video monitor is supported and can be lowered into the cabinet gradually. A blind mating connector connects the video monitor to the logic for controlling the game.

Description: Background Of The Invention The invention relates, generally, to video game machines and, more particularly, to a device for facilitating the insertion and extraction of the video monitor into and out of the video game cabinet. Video games typically consist of a game cabinet supporting a video monitor and a plurality of player operated buttons. The video monitor displays a game as directed by the game program and the player manipulates the buttons to control play of the game. The player operated buttons preferably consist of video "buttons" displayed on the monitor for screen touch control although electro-mechanical switch buttons located on the cabinet can be used, if desired. While such video game machines are used to play a wide variety of games, such as games with sporting or fantasy themes, the use of video game machines for gambling purposes has risen dramatically in recent years. Such games are commonly found in casinos and other legalized gambling sites where games such as poker, blackjack, keno and the like are played. In some video game machines the video display consists of a video monitor arranged with its screen substantially vertical. In other video game machines the screen is arranged at approximately a 30 degree angle relative to the horizontal. These, so called, slant top video game machines are commonly used for gambling applications where the game player sits in front of the machine and the game cabinet is dimensioned somewhat like a desk. In slant top machines the video monitor is typically lowered into the game cabinet through the top. Because the typical video monitor weighs approximately 23 kg (50 pounds) and is cumbersome to handle, it is very difficult for the game operator to insert and remove the monitor from the cabinet. This poses a significant problem because video monitors are periodically removed for repair and maintenance purposes. EP546477 discloses a built-in monitor such as an electronic gaming machine, having a rectangular picture screen disposed in a casing, the screen being turnable in an angle of up to 90°, and a complex arrangement of rails and corresponding rollers is provided to accommodate the repositioning of the screen. Thus, a video game machine that facilitates the insertion and removal of the video game monitor is desired. Summary of the Invention According to the present invention, there is provided a video game machine, comprising: a) video monitor having an engagement means, b) a game cabinet defining an internal space for receiving said video monitor, the space having at least one monitor support plate, the game cabinet having at least one track, characterized in that the engagement means includes a first engagement means and a second engagement means extending from said video monitor, and the at least one monitor support plate includes a first and second monitor support plate, opposing one another and located on either side of the monitor, each of said first and second monitor support plates include the at least one track, the at least one track characterized by a first track and a second track for receiving said first and second engagement means, said first and second tracks being arranged such that said first and second engagement means slide in said first and second tracks, respectively as said monitor is inserted into the space and such that the video monitor is supported in a first position where the monitor is removed from the space, a second position where the monitor is fully inserted in said space, and a third position intermediate said first and second positions.

Figure 2 is a partial perspective view similar to that of Figure 1 showing the video monitor partially removed from the video game cabinet. Figure 3 is a side view of a typical video monitor. Figures 4a-4d are side views showing the monitor of the invention as it is inserted into the cabinet. Figure 5 is a schematic view of the internal cabinet space for receiving the monitor. Figure 6 is a section view taken along line 6-6 of Figure 3 showing the handle of the invention. Detailed Description Of The Invention Referring to Figure 1, the slant top video game machine of the invention is shown generally at 1 consisting of a cabinet 2 having an inclined top 4 under which the video monitor 6 is located. A plurality of player operated switch buttons 8 may be provided on the cabinet 2 allowing the game player to control play of the game. Alternatively, the game can be controlled by "buttons" displayed on the video monitor 6 for screen touch control as will be understood by one skilled in the art. A dollar bill collector 8 and coin trough 10 are provided to receive the player's money and deliver payouts, respectively. Referring more particularly to Figure 2, the cabinet top 4 includes a door 12 that can pivot between the closed position of Figure 1 to the open position of Figure 2. The door 12 is provided with an aperture 14 that allows the player to view and touch the video monitor 6. In Figure 2, the video monitor 6 is shown partially withdrawn from the cabinet 2. The video monitor 6 includes a video screen 18 attached to a protective steel casing 20 which houses the monitor electronics including the high voltage power supply. The steel casing 20 includes two sets of handles, the functions of which will be hereinafter described. The first set of handles consists of a pair of cables 22 and 24 where each cable extends across the monitor and is connected to either side of casing 20. Cable 22 is located at the top edge of the monitor and cable 24 is located at the bottom edge of the monitor. The second set of handles consists of cut out handles 26 located in casing 20 on either side of monitor 6. While only one cut out handle 26 is illustrated it will be appreciated that a second identical handle is located on the opposite side of casing 20. Referring more particularly to Figure 6, the handle 26 is shown in greater detail. Located in cutout 26 is a protective flap 28 pivotably mounted to casing 20 at pin 28. A torsional spring 38 forces flap 28 outwardly.to the position illustrated in Figure 6. When the monitor is inserted into the cabinet, the flap 28 will protect the operator's fingers from striking the support plates of the cabinet. When the operator's fingers are removed from cut-out handle 26, the support plates 42 and 44 of the cabinet will contact the flaps and overcome the force of spring 30 to close the flaps. The flaps 28 will return to the illustrated,open position once the monitor is removed from the cabinet. Referring to Figure 3, one side of monitor 6 is shown where three lugs 36, 38 and 40 extend from casing 20 a short distance. The lugs are arranged along the bottom edge of the casing 20 with lugs 36 and 38 located near the front of the monitor and lug 40 arranged near the rear of the monitor. The specific location of the lugs will be described with reference to Figures 4a-4d. While only one side of monitor 66 has been described, it will be appreciated that the opposite side of the monitor is identical. Located on the back of the monitor casing 20 is a blind mating electrical connector 39 for mating with a corresponding connector 41 located in the cabinet. Referring to Figures 2 and 5, the monitor 6 is located in an internal space 45 in cabinet 2. On either side of internal space are identical support plates 42 and 44. The support plates 42 and 44 are spaced from one another such that the monitor will fit therebetween but the lugs 36, 38 and 40 on the monitor will contact the plates. The internal space is further defined by front wall 43, back wall 51 and bottom 49 where bottom 49 supports electrical connector 41 as best shown in Figure 5. Support plate 44 is shown in detail in Figure 4a and monitor 6 is shown in dashed line. It will be understood that support plate 42 is identical in structure and operation to plate 44 such that only plate 44 will be described in detail. Support plate 44 includes a first track 48 that is substantially linear and extends at approximately a 60° angle relative to the horizontal top edge 47 of plate 44. A second track 50 is formed in plate 44 behind track 48 and has a complex shape. Track 50 includes a first curved section 52 and a second linear section 54. Curved section 52 comprises essentially an arc of a circle where the center of the arc is approximately the top center of track 48 and includes a recess or lug support 56. Linear section 54 extends from section 52 and is aligned with first track 48. Referring more particularly to Figures 4a-4d, the installation of the monitor in cabinet 2 and the interrelationship between the lugs and the side plates will be described. While only support plate 44 is illustrated and referred to, it is to be understood that the arrangement and operation of support plate 42 is identical and that the insertion steps described with reference to plate 44 occur identically and simultaneously relative to plate 42. Referring to Figure 4a, to insert the monitor, the game operator grips cut out handles 26 and sets the monitor in cabinet 2 such that lugs 36, 38 and 40 rest on support plate 44. Lugs 36 and 38 rest on the top edge of plate 44 while lug 40 rests in recess 60 that is contiguous with track 50. Handles 26 are grasped and monitor 16 is moved backward (as shown by Arrow A in Figure 4a) until lug 40 is located in track 50. The monitor 16 is pivoted as shown by Arrow B in Figure 4b until lug 40 engages and rests on recess 56. In this position the handles 26 can be released as the monitor 16 is fully supported by the engagement of the lugs with the side plates. The operator then grasps cables 22 and 24 and pulls up on the monitor (as shown by Arrow C in Figure 4b) to release lug 40 from engagement with recess 56. The monitor is then allowed to rotate (as shown by Arrow D in Figure 4c) until lug 40 is located above track section 54 and lugs 36 and 38 are aligned above track 48. The monitor is then lowered as shown by Arrow E in Figure 4c until the lugs 38 and 40 rest on the ends of tracks 50 and 52, respectively, as shown in Figure 4d. Pressure is then exerted on the monitor in the direction of Arrow E to ensure that the blind mating connectors 39 and 41 are fully engaged. To remove the monitor 6 from the cabinet, the steps described in reference to Figures 4a-4d are reversed such that the monitor can easily be removed. As will be apparent, the monitor mounting structure of the invention allows the monitor to be easily inserted into and removed from the game cabinet while ensuring that the monitor is properly aligned. Moreover, because of the unique shape of the tracks the monitor is fully supported on lugs 36, 38 and 40 at positions intermediate the fully inserted or fully removed position. While the invention has been described in some detail with reference to the figures, it will be appreciated that numerous changes in the details and construction of the device can be made without departing from the scope of the invention as defined in the claims.
